Hi!

I really need your help guys.
I installed some drivers for my iphone, install with no props, when asked to restart, I do.

(This have nothing to do with the iPhone)
When computer automatic power on, no screen is shown, no boot, and all LED's is on.

1st try:
I let i stay that way for 20 mins, when i look to it, the fan is running like hell, and ite hot! - FAILED

2nd:
I let it cool off, and try to power it on with alt key pressed - FAILED

3rd:
I take out AC, then battery and hold down power button for one minute, plug in AC and try again - FAILED

4th:
I take out HD, RAM, RTC battery, let it stand empty for and hour, put it all back - FAILED

5th:
I try to take out only RAM's and plugged them back in every diffrent way i could - FAILED

6th and last:
Plugged out HD, turned on the computer, and it acted like it never had been removed - LOL?

Im pretty stucked right now, all tests has been done in every diffrent way, with AC in and out.
Also had tried with boot cd in, and have read so many post here and on HP support with no luck.

Oh, and its a HP Pavilion DV6 - 2150so
OS: Windows 7 Home Premium x64

HELP!!!!!! :-)

I have almost the exact same model as you, Pavilion DV6 - 2140ca.  Had the exact same problem.

My wife kept the power button held down extra long and the unit beeped at us.  When I then attempted a normal startup it fired up no problem.  Give it a try.  I am willing to bet it was a heat problem.  Getting annoyed with this machine as we have had 3 breakdowns in the past 2 months on this, now, 8 month old laptop.

Did u get any help from HP? Printing photos and computer restarted and did not come back up. keeps saying I/O error.

HELP!!!!!!!!!!!!!

Mine comes back on if I remove the battery, and  the power cable. Then keep hitting the on/off button until no lights come on. Then I plug in the power and it boots up and eventually I remember to put the battery back in.

What I would like to know is how to stop it doing this.

I had the same problem blank screen but led lights and fan on for only a second. 6 months gone bye . hundreds of articles read, watched many you tube vids. download many service and user manuals from hp nothing. then i thought my laptop had the problem like the dv6000,dv9000, tx series with the graphics processor rohs solder i was about to give this computer to a friend to rip apart when on my birthday i see this tech bulletin it said press power button and escape button to get to a recovery  page . well i grabbed the computer  pressed the start button then the esc button nothing, then press both buttons at the same time presto screen comes on asks me to repair computer or start windows normally . i chose repair  I almost @#%$ you think they would have this on there trouble shooting page in stead of taking memory modules out ,disconnecting hard drives ,taking battery out and holding power button down. well it been a couple of days  and writing this from the dv6-2150 that had the problem . well good luck all merry Christmas and if i didnt see that article on the hp site   smack me in the back of the head  . duhhh!!!!!!!!!!!

noway444 was absolutely right..pressing the start & esc button together powered it up briefly.. then did the same process again taking the laptop close to a fan.. and that did the trick.. you guys saved my day..

If your HP DV6 suddenly won,t start, check if you have got anything connected to it. I was preparing for my Structures exam and last night i left my DV6 on, this morning when i wanted to start it, it won,t start and would only show the HP logo, nothing would work. Then i disconnected the power supply, took the battery out and disconnected the Eposon Stylus printer which was connected to it last night. When i turned it on with only the AC power, it went through. The moral of the story is "Do Not Panic, Check Your Connected Devices- HP might not like them all."

Thanks to noway444, i did panic myself though but you saved my day and probably my computer, because i smashed my old HP literally in the face ( with mouse) about 3 months ago  as it wont write me a CD and it was 3 in the morning.
